This study specifically examined the utilization of green materials for concrete in Singapore, Malaysia, Indonesia, Thailand, and Vietnam. Construction, being a material-intensive sector, consumed vast amounts of natural resources and generated substantial waste and harmful emissions, posing significant environmental challenges. In response, sustainable development initiatives were prioritized across ASEAN nations to address these issues. Governments and relevant authorities implemented various strategies to promote sustainable practices in construction, including providing financial support to both public and private sectors. Among these practices, the adoption of green materials for concrete stood out as a promising approach for sustainable development in the construction sector. By incorporating recycled aggregates, supplementary cementitious materials (SCMs), and other environmentally friendly alternatives, these countries aimed to reduce resource consumption, minimize waste generation, and mitigate environmental impact. Embracing sustainable construction practices not only promoted environmental stewardship but also contributed to long-term economic viability and social well-being in the ASEAN region.","PeriodicalId":186610,"journal":{"name":"Tropical Environment, Biology, and Technology","volume":"3 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141378498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, some aspects of the Biology of Sarotherodon melanotheron and Tilapia guineensis in the Mahin Lagoon were covered in this study. For the study, 121 fish samples were collected. The sex ratio of S. melanotheron (1:1.64) and T. guineensis (1:1.36) showed no significant deviation from the expected 1:1. Fecundity ranged from 243 to 1223 in S. melanotheron and 156 to 600 in T. guineensis with means of 344.39±166.85 and 286.27±114.85 respectively indicating low fecundity in both species. Observed Gonado-Somatic Index (6.40±3.25% for T. guineensis and 5.65±3.31% for S. melanotheron) suggested the peak of gonad maturity. The regression equation of the length-weight relationship indicated that S. melanotheron exhibited negative allometric growth in male (b=1.66, R2=0.63), female (b=2.80, R2=0.83) and combined sex (b=2.55, R2=0.78) while T. guineensis exhibited positive allometry in male (b=3.05, R2=0.97), female (b=3.04, R2=0.95) and combined sex (b=3.04, R2=0.96). The condition factor was greater than 2 for both species. This study also revealed that the fecundity of the two species was size dependent. Examination of stomach fullness revealed that 4.2% and 0.0% of S. melanotheron and T. guineensis had empty stomachs while 20.0% and 3.8% had full stomachs respectively. This study therefore established that the study area was conducive for the fish. Monitoring and regulation of the fisheries is therefore recommended for conservation and management of the study area.   ","PeriodicalId":186610,"journal":{"name":"Tropical Environment, Biology, and Technology","volume":"60 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139530654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Though seemingly unrelated, they intricately influence each other. This review aims to present the intricate connections between climate change and plastic pollution through the review of recent literature in these genres. The review explains that global warming could increase plastic degradation through physical, chemical, and biological processes, leading to an increased abundance of microplastics. Global warming enhances the leaching of chemicals from microplastics. Higher temperatures promote desorption of chemicals sorbed on plastics by providing the adsorbates with more kinetic energy to overcome attractions with the adsorbents. Higher temperatures can also promote biofilm formation and alter the microbial community structures of biofilms. Melting sea ice and glaciers associated with warming temperatures release the microplastics trapped in the environment. Sea-level rise and extreme weather events enhance the transfer of microplastics between land, ocean, and air, thus changing their distribution and transport, while ocean acidification may influence the biofouling of microplastics and increase the vulnerability of some corals to the impacts of microplastics. Plastic pollution, however, exacerbates climate change due to the release of greenhouse gases throughout the lifecycle of plastics. Microplastics also adversely affect the growth of microalgae, hence the ocean carbon cycle. Airborne microplastics can alter the energy balance of the Earth through scattering and absorbing radiation. This review suggests a circular economic approach to minimize waste, maximize the reuse and recycling of plastics, and promote the use of plastic substitutes to address both issues.","PeriodicalId":186610,"journal":{"name":"Tropical Environment, Biology, and Technology","volume":"35 13","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138593842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In both the rainy and dry seasons, soil samples were taken from a farmland at the University of Benin in Nigeria at depths of 0–15 and 15–30 cm, respectively. The physicochemical parameters investigated include pH, EC, carbon content, nitrogen, organic matter, phosphorus, aluminum, and Cation Exchange Capacity (CEC), as well as Ca, Mg, K, and Na. When comparing seasonal differences in pH, phosphorus, aluminum, and CEC levels, significant differences were revealed at ρ < 0.05, d = 0.0001 for pH, ρ < 0.05, d = 0.0001 for phosphorus, ρ < 0.05, d = 0.0002 for aluminum, and ρ < 0.05, d = 0.019 for CEC, respectively. Conversely, the seasonal differences in EC, carbon content, nitrogen, and organic matter were not significant at ρ < 0.05, d = 0.46 for EC, ρ < 0.05, d = 0.30 for carbon content, ρ < 0.05, d = 0.46 for nitrogen, and ρ < 0.05, d = 0.31 for organic matter, respectively. The investigated soil physico-chemical properties did not vary significantly according to land use types at ρ and d values.

A total of six swabs were aseptically collected randomly from different parts in the respective aprons of food vendors from six randomly selected street food vendor points within the premises of the study area. The isolates' cultural and morphological characteristics were identified. Four bacterial and six fungal isolates were found in the aprons. The bacterial isolates include Staphylococcus aureus (32.7%), Bacillus spp.(21.8%), Klebsiella spp.(11.1%) and Escherichia coli (34.01%) while the fungal isolates include Mucor spp. (12.1%), Candida spp. (17.1%), Microsporum canis (17.1%), Penicillium spp. (9.7%) and Aspergillus spp. (24.3%) for fungi were isolated. Escherichia coli and  Aspergillus species were the most prevalent bacterial and fungal isolates respectively. It was observed that aprons of food-vendors who stay in close proximity to garbage dumps contained higher levels of pathogenic organisms. The results of this study showed that most food vendors fail to maintain proper food hygiene, which raises concerns for the public's health. Education of food vendors on personal, environmental, and food hygiene is crucial since it will help to reduce apron contamination and improve the safety of the food provided at vending locations.","PeriodicalId":186610,"journal":{"name":"Tropical Environment, Biology, and Technology","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139212074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microplastic particles range in size from 1 to 5 microns and are the result of the breakdown of larger, original plastic particles. Microplastic was defined in 2011, but the majority of people did not view it as a serious pollutant or act accordingly. Microplastic is a serious pollutant that has prompted increased research and experimentation since 2005. Microplastics are so small that they can enter the tissues and organs of aquatic animals. Malaysia produces a quantity of plastic waste and receives plastic waste from other countries for disposal. The effects of microplastic on aquatic animals have been studied in relation to the ecosystem cycle and food chain. The presence of microplastic in aquatic animals has detrimental effects on the environment, human health, species health, and the ecosystem. Physical, chemical, and biological technologies are provided, as well as a combination of two technologies, for the remediation of microplastic, which aids in the removal of microplastic from the environment and the reduction of microplastic in aquatic animals. These technologies aim to reduce the concentration of microplastics in water bodies, preventing their ingestion by aquatic animals. However, their efficiency in tropical regions may vary, depending on the specific environmental conditions. It requires continued research, policy, and public awareness to mitigate the impacts of microplastics on the environment and human health. In addition, microplastics generate some challenges and opportunities for reducing microplastics' impact on humans and the environment in the future.","PeriodicalId":186610,"journal":{"name":"Tropical Environment, Biology, and Technology","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132664473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary objectives of this study are to investigate the quantity and distribution of microplastics in water and riverbank sediments, as well as to analyze the properties of microplastic particles in the Kemena and Niah rivers. The selection of these rivers was based on the presence of commercial, residential, and industrial areas along their lengths. A total of 24 water and soil sediment samples were collected from three different sites along the Kemena and Niah rivers. The concentration of microplastics in water samples ranged from 60 to 128 items per liter, while sediment samples ranged from 46 to 76 items per liter. The sediment samples also contained microplastics ranging from 21 to 40 and 45 to 125 items per kilogram. Microplastics were observed in various forms, including fibers, films, foam, and fragments, in both water and soil sediment samples. The majority of microplastics were between 0.1 and 1 mm in size, with blue being the most common color observed in river water and transparent in sediment samples. The ATR-FTIR spectrum analysis indicated the presence of four distinct polymers: polyethylene (PE), polystyrene (PS), polycarbonate (PC), and polyethylene terephthalate (PET).
